Plate 2, fig. 2. Teacher-Bryce Ovum No. 2

The lobule enlarged to about X15. This should be examined along with text figure No. 1 on page 174.

The text figure shows the principal structures in outline as they appeared during clearing in Xylol. The landmark is the oval blood clot (marked “ clot ”). The cross beside it indicates the centre of the aperture of entrance and operculum. The area enclosing the cross represents the extent of the adherent cone of blastocyst. The operculum is considerably more extensive. The oval bodies below it are the ends of chorionic villi and the dark bodies Show the masses of uncleared blood in the superficial vessels. The clear area of the figure represents fairly accurately the avascular decidua capsularis. G1. 1 and G1. 2 indicate the nearest glands.

Both figures drawn by A. K. Maxwell.
